ROPE-CLAMP.

Specification of Letters Patent.

,Patented April 2, 1907.

Application filed March 20, 1906. Serial No. 306,971.

To @ZZ whom it may concern,.-

Be it known that I, CHARLES W. GUTTZEIT, a citizen of the United States, residing in High Bridge, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Rope- Clamps, of which the following is a speciiication.

This invention relates to clamping devices, and is articularl y designed for use in clamping a s eeve or the like member upon a cylindrical body, such as metallic rope or cable.

The objects of the invention are to provide an .improved form of clamping device in which the longitudinal movement of one member upon other members will serve to clamp the device upon the rope or cable and also to provide an additional clamping means that is readily adjustable to accommodate various diameters of cable and which device is very simple in construction and operation, so that the clamp can be very quickly attached and detached, and which will not tend to cut or kink the strands of the cable, but

rovide uniform pressure throughout the ength of the clamp.

In the accompanying drawings, represent ing one embodiment of my invention, Figure 1 is a section taken through the axis of the device, showing the clamp locked on a cable. Fig. 2 is a section on the line 8 3 of Fig. 1, and Fig. 3 is a section on the line 2 2 of Fig. l.

The device as illustrated comprises an outer tubular member or sleeve 5, whose eX- terior may be of any desired form, being shown as cylindrical, hut provided at one end with an enlargement or bead 6. The bore 7 of the sleeve 5 is made tapering and is shown as converging from the bead end to the other end. Between the wall of the bore 7 and a cable S are arranged a pluralityT or series of wedge members. These members are tapered in the o posite direction-that is, the smaller end is ocated at the end of the sleeve opposite the beaded end. By forcing these wedge members in the sleeve they will tightly clamp the cable 8 on account of their wedge or tapering shape and the inclined bore of the sleeve. In the form shown there are four wedge members 9, 10, 11., and 1.2, that are ar- These four members inclose a substantially cylindrical space, and

therefore tightly grip the cable, as shown in Figs. 2 and 3. The outer faces of the wedge members together for/m a cone-frustum, and the bore of the sleeve 5 is rovided with a similar conical form. By tiis means when the wedge members are simultaneously moved longitudinally in the sleeve in one direction they will move radially inward and tightly grip the cable 8. Sufficient space 13 is provided between the adjacent edges ofthe wedge members, so that when the wedge members are drawn together by the sleeve and clamping means and engage the cable or other member in their interior their adjacent edges will not be brought into engagement.

In order to lock the four Wedge members together and cause their simultaneous movement relative to the outer sleeve, suitable locking means is provided at one ,end of the segmentary wedge member. The larger end of the wedge member is arranged to project beyond the entering end of the sleeve and is there provided with an annular or eri heral groove 14. A U-shaped clamp an bo t 15 is provided to press one-half of this groove, as shown in Fig. 3. A clamping-block 16, hav ing apertures 17 and 18, is inserted on the ends of the bolt, as shown, and has a curved portion 19, arranged to engage the side of the groove opposite that engaged by the bolt. Nuts 2O and 21 screw on the ends of the bolt against the block 17 and serve to tightly clamp the members of the segmentary Wedge in position andagainst relative longitudinal movement.

When it is desired to attach the clamping device, the wedge members are placed around the cable and the clamping bolt and block placed in position and secured by the tWo nuts. Thereupon the sleeve is slid on the cable from one end and the smaller end of the wedge member is inserted in the larger end of the sleeve-bore and then the wedge is driven home in the sleeve. It will be observed that the wedge members can be attached at any part of the rope and do not require to be inserted on one end of the rope.

Having thus described my invention, I claim- A rope-clamp comprising a sleeve, a series of wedge members in the sleeve cooperating with the bore thereof to clamp the rope ICO against longitudinal movement, the Wedge portions of the other Wedge members, and members projecting beyond the sleeve at nuts on the bolt ends engaging the block and their larger ends and provided With a perpl1- securely clamping the Wedge members.
